Confluence requires URL rewriting for proper functionality. If Confluence is accessible via different domain names without URL rewriting, you will experience an array of problems. See Various Issues Caused when Server Base URL Does Not Match the URL Used to Access Confluence.

In some cases, you may wish to access Confluence from different domains.

To configure Confluence over multiple domains,

  1. Add a DNS entry mapping http://wiki to the externally visible ip address of the Confluence server.
  2. Configure Confluence's server base url to http://wiki.domain.com.
  3. Add Apache HTTP proxy, using the instructions from Running Confluence behind Apache.
  4. Add the mod_rewrite module, to change the URL.
